摘要： Method and apparatus for extending functionality of a first set of classes and methods in an application hosted by a computing arrangement. A mapping is established that maps original class names in the first set to corresponding substitute class names of classes in a second set. The classes in the second set change the functionality of the classes in the first set. In response to loading a class file of a class in the first set, the original class names are replaced with corresponding substitute class names in the class file. Classes referenced by the substitute class names are then instantiated in lieu of classes referenced by the original class names.

摘要： Method and apparatus for managing memory of a data processing system. In one embodiment, memory objects are allocated in response to memory allocation requests. Each object has an associated plurality of addresses. Type-identifier codes are respectively stored in association with the memory objects. Upon detection of a transient memory error at a memory address a recovery action is selected and performed based on the type-identifier code of the object that is associated with the erring memory address.

摘要： A method for offloading execution load from a resource-constrained device to allow the device to run a resource intensive software program. A program is accessed using a first device and determines whether execution of the program will exceed resources of the first device. If the execution will exceed the resources of the first device, a load split is determined to split the program into a first portion and a second portion. The second portion of the program is offloaded to a second device, while the first portion of the program is retained on the first device. The first portion and second portion communicate via a network connection. Full program functionality is provided using the first device, wherein the functionality is provided by the first portion and second portion executing respectively on the first device and the second device.

摘要： A system and method for memory failure recovery is disclosed. The method discloses the steps of maintaining a predetermined number of duplicate and primary processes; keeping the processes in synchronization; managing the processes so that a single process image is presented to an external environment; detecting a computer system exception which affects one of the processes; and terminating the affected process. The system discloses, a primary process memory space which hosts a primary process; a duplicate process memory space which hosts a duplicate process corresponding to the primary process; a synchronization buffer which keeps the duplicate process in synchronization with the primary process; a processor which generates an exception signal in response to detection of a memory failure condition which affects the primary process; and an operating system which receives the exception signal, terminates the affected primary process, and maintains a predetermined number of primary and duplicate processes.
